Behind the Curtains of Making Real Consumer Devices using Debian
summary
Starts from vendor BSP, extracts binary blobs, then stitches a custom image with devos recipes to replace the rootfs first and rebuild bootloader and kernel patches; uses GitLab CI (or GitHub/Jenkins) for reproducible builds and nightly runs, OBS to produce Debian packages, LAVA for hardware CI, and RAUC A/B upgrades plus OSTree for OTA. Locks down serial consoles, converts root to read-only and protects it with dm-verity read-only rootfs; factory flashing and provisioning run from a dedicated PC.
